TYPE-CASTING MACHINE.

Application filed June 6, 1912.

To all whom it may concern Be it known that I, J OSEPH FREDERICK NORMAN,a subject of the King of England, residing at London, in the Kingdom ofEngland, have invented a new and useful Type- Casting Machine, of whichthe following is a specification.

This invention relates to that kind of type casting machine in which aplurality of matrices and molds are carried on a sliding carrier andsuccessively brought before the orifice of a pot containing molten typemetal so that each type is cast separately and after being nicked andtrimmed is ejected from the molds.

It is my object to provide a simple and reliable machine of this kindwhich is double acting and will perform the work in an expeditiousmanner, and I obtain this object by adopting a straight bed fitted withan endwise reciprocating carrier furnished with transversely slidingmatrices between fixed molds connected with said carrier and travelingover a stationary mold plate, said matrices being controlled by camssituated at each side of the headstock for ejecting the finished typeone after another.

The invention is illustrated in the accompanying drawings, in whichFigure 1, is a front elevation of the left half of the machine, theright half being identical to the former; Fig. 2, is a correspondingplan; Fig. 2 is a portion of said plan drawn to a larger scale and withthe top parts removed; Fig. 3, is an end elevation of same to a largerscale but with the matrices omitted; Fig. l, is a cross-section at themiddle of the machine; Fig. 5, is a cross-section taken at the point ofejection of the type; F igs. 6 and 7 are a plan and a side elevationrespectively, to a larger scale, of a fixed side of the mold; Figs. Sand9, are a side elevation and plan respectively of a matrix havingadjustable heel-studs and Fig. 10 is a partial plan view of the machine.Fig. 11 is a perspective view partly in section of the various moldparts, showing both the mold sides and matrices, and Fig. 12 is a likeview with the near mold side omitted.

The same reference characters denote the same parts throughout all thefigures.

The liquid metal pot, pump and heating device are not shown in thedrawings as these parts are well known in connection Specification ofLetters Patent.

with type casting machines and would here take up unnecessary space.

The frame 1 and stationary bed 2 of the machine are of any suitable formand size and the bed 2 carries in a longitudinal recess a traveling moldcarrier 3 with attached mold sides 9 which latter pass between astationary upper mold-part 4 and an undermold 5, the latter beingwater-jacketed at 6 so as to receive circulation of a cold water currentfor cooling the freshly cast type. Refrigeration is also provided, bymeans of the tubes 7* and jacket 22, for the removable headstock 7 whichis well known and forms no actual part of this invention but helps toidentify the type of casting machine referred to and indicates theposition of the induction nozzle 8 for the molten type metal. The uppermold part 4 is attached to the underside of the headstock, or to a partconnected with the latter as will be explained.

' The under mold part 5 consists of a stationary plate of hard steelformed with sides 5" tightly fitted in the box or water jacket 6. Thelength of the stationary under-mold part 5 and box 6 is about equal tothe length taken in each direction by the traveling set of mold partsand intervening matrices. The width of the under-mold part 5 is slightlymore than usual typeheight. The mold sides 9 are made of steel andextend beyond the under-mold part 5 by the. width of the carrier 3 towhich they are adj ustably fixed by screws 11 and shaped nuts 12, whichlatter are lodged in grooves 13 of the carrier 3. The carrier 3 has atits underside a rack 14 which is moved through the intervention of gear15 actuated either by the handwheel 15* or by power as is usual in othertype-casting machines. Between the suitable spaced fixed mold-sides 9are placed slidable matrices 16 each fitted with a screw stud 17 foradjusting the matrices .111. relation to their engagement with cams 19and 23.

The lower portion of each matrix 16 is of type width or thickness andfits the thin end portion 9* of the mold sides 9, while the upperportion of the matrix is wider so as to allow the drilling for the stud17 without being weakened. The length of a matrix is such as to providea space equal to typeheight when the matrix is slid inward. Forimparting sliding motion to matrices, the

upper portion of each matrix is shouldered as shown so as to move withthe forward shoulders 16* and the rear stud 17 between the front andrear cam surfaces 18 and 19 connected with a stati mary cover plate 20fixed to the bed 2 oi the machine by screws 21. The cams 18 and 19 causethe matrices to slide between the mold sides 9 crosswise of the machinewhile traveling with the mold carrier 3 longitudinally of the bed of themachine. A plate '20 with identical cams 18 and 19 is fixed toward eachend ot the machine at a suitable distance from the middle and betweenthese two plates the headstock 7 is fixed. In front of the headstock isfixed a hollow watercooled jacket 9.2 to the underside 01'' which isfixed the aitorenientioned plate 4. which fits accurately over the frontportion 9* ol the mold sides 9 'andso closes same at the middle portionof the machine to receive the metal squirted in from the induetionnozzle 8 separately into each recess l'lQtWL-ltll the mold parts as theypass along the bed of the machine. ilhen a mold side 9 is in front ofthe nozzle 8, the corresponding matrix is positioned in vard and itsrear shoulder touches against a gradually curved cent al cam 23 whichaccurately sets the matrix to the required height o'l type the adjustingstud 17 of the matrixbeing at this period notin action. The upper moldpart is has a head 22* to form a groove. 7

After the type has been cast, cooled and nicked during a portion of itstravel in the longitudinal direction of the machine, it arrives at anopen slot 2* of the bed 2 beneath the cam 18, so that it can begradually ejected from the mold by the matrix which is now pushed inthis direction by the twin cams 18 and 19 fast in the plate 20. At themomentwhen the type is fully projected from the slot it is taken up by atraveling belt and carried with other type to a receptacle in the usualmanner. After the last type from the previous casting operation has beenccted, the movement of the machine is reversed and the carrier 3 takesthe molds in the direction toward the opposite end of the machine so asto repeat the entire cycle oi operations, the parts at this side of themachine being the exact counterparts, to those previously described.
